CS 50 is a first course in computer science for concentrators and non-concentra- tors alike. More than just teach you how to program, this course teaches you how to think more carefully and how to solve problems more effectively. As such, its lessons are applicable well beyond the boundaries of computer science itself. That the course does teach you how to program, though, is perhaps its most empowering return.

The climax of this course is its final project, an oppor- tunity to take your knowledge of programming out for a spin and develop your very own piece of software.

On exhibition today are the accomplishments of Fall 2008’s 330 students.

This is the CS 50 Fair. This is CS 50. the raffle Whether you are a student in CS 50 or just here to see some projects, you are eligible to partake in today’s raffle. Earn stickers from presenters and earn chances to win! Step 0: Ask each presenter whose project you see for a
